A new trailer for Thor: The Dark World has been released across YouTube as part of the video-sharing website's Geek Week celebrations.

The Marvel sequel to the 2011 hit sees Chris Hemsworth and his hammer reprise their respective roles as the Norse God of thunder and a massive hammer to face off against Christopher Eccleston's Malekith and the Dark Elves.

Natalie Portman is on board once again as astrophysicist Jane Foster, while Tom Hiddleston returns as Thor's scene-stealing adoptive brother Loki.

Other famous faces that can spotted in the two and a half minute trailer include Idris Elba and Sir Anthony Hopkins. Rene Russo, Adewale Akinnuoye-Agbaje, Kat Dennings and Zachary Levi are also in the cast for the eight instalment in the Marvel Cinematic Universe.

Directed by Alan Taylor, the blockbuster will open in UK cinemas on October 30.
